Quoting the number at a service desk can save a diagnosis.

Read by machine from the document NHTSA serves (9 pages), read Sep 30, 2026. A part number is shown only where it matches BMW’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

Source: NHTSA complaint databaseOwners of the 12 model years this bulletin names have filed 231 complaints with NHTSA since 2015. 3 of them name Exterior Lighting — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.

Common questions
Source: NHTSA, 49 CFR 579.5Is BMW B631123 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the B631123 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every BMW warranty extension on file lists the ones BMW has filed.
Which vehicles does B631123 cover?
The manufacturer filed it against 13 model years: 2025 BMW 7 Series, 2024 BMW 7 Series, 2023 BMW 7 Series, 2022 BMW 7 Series, 2021 BMW 7 Series, 2020 BMW 7 Series and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
